It would be very helpfull to modify the LAN-C control of the BMPCC with the Z15 gimbal.

My sugestion is to change AUX3 from 2-position to 3-position.

Pos-2 -> Pos-1 Starts recording
Pos-1 -> Pos-2 Stop recording
Pos-2 -> Pos-3 sets focus

BMPCCC allows this control on the LAN-C port, so please add the funktion to the Z15.

Thanks for your suggestion.

Did this ever get incorporated?

I am sure it probably didn't.  There are quite few things we have suggested be updated but looks like they are focusing their efforts more on phantom & inspire than their professional Spreadwings which are more expensive equipment.  

I wouldn't hold my breath.
